RAIL TIE.

Ap maon as September 2 1924. Seria,1No.l739,497.

. '1 70 all zcizfom it mag) concern:

Be it known that I, CHAnLns Jones, a sub ject of thel King of Great Britain and Ireland, residing at Sidonia, 26 Marshall Street Chilwell, (:teelong, in the State of Victoria, ti'ommoiiwealth ofAustralia, have invented certain new and useful Improvements in Rail Ties; and I do hereby declare the following to be a' full, clear, and exact description of the invention, such aswill en able others skilled in the art to which it appertains to make and use the same.

By this inventionl improve upon perma nent way rail ties made of reinforceidconcretev "lclaim no particular concrete mixture, but prefer to use as an ingredient pumice stone to reduce weight,the reinforcement ensuring strengtl'i. The concerete isno-t neoessarily of the same quality throughout, as its surfacing may advantageously be of stronger and of moreWaterproof cementitious materials than the interior.

My rail tie is of compound block type, that is there are two main blocks, each of any desired pattern and dimensions, connected as will be described.

In the drawings herewith I illustrate my rail tie, but there could be modifications of some of the details shown within the scope of my claims.

Figure 1 is a plan of the rail tie. Figure 2 is a front view of the rail tie. Figures 3 to 6 are on a larger scale. Figure 3is a perspective view of one of the concrete blocks.

Figure 4 is a perspective view showing the two blocks connected, also showing one block elongated. t

Figure 5 is a view in section of part of a rail tie under a chair which is under a rail the base of which is shown.

Figure 6 is a plan of the parts in Figure 5, but with the nuts and washers removed.

The concrete blocks are most easily transportable before they are connected; connection can be made at the place of laying; the rail tie will then stand hard usage.

In these drawings 1, 1 are blocks of reinforced concrete, either or both being when desired elongated. Each has a top surface 1 on which will be located a chair 3 of suitable resilient material, as rubber, under a stems 4 of suitable, as of rectangular, section,- there are holes 5 in each block; and there are recesses 2 in the rail webs 2lwl1en desired to enable each rail 2 to be restrained fromcreeping longitudinally. l

' Each bolt shown with a plain washer 4", a resilient washer l, and a fastening nut 4. The space around each bolt will in some cases be filled with grouting,

On the underside ofeach block I provide at will ribs 1 extending across the rail tie. These ribs are a form of rougliening of the surface their purpose being to grip the ground or foundation.

1n eachblock 1. I I embed the bodies of longitudinal reinforcing bars 7. each bar having ends 7 which project at the respective ends of each block. These ends are to be coated with anti-rust materialinsuitable cases. These bars are made irregular, as by twistingat 7 the irregular parts being embedded in the concrete to resist tendencies to longitudinal displacement of the bars. In each block there is also reinforcement 8 which connects the bars all the said reinforcement being. assembled in a suitable mould, before all the concrete is added.

All the projecting ends of bars 7 are usable as handles for facilitating transport of the blocks until the latter are connected; but when connected, the outer end projections only are so usable.

To form the rail tiesof two blocks with. intermediate connections the blocks are assembled, and. those bar ends which are then central are connected by attaching bars 9, as by bolts 9 Sets of bars 9 are then bolted together; thus 10 are screw-threaded bolts, each carrying a pair of outer nuts 10 and a pair of inner nuts 10. The spacing apart of bars is regulated by positioning these nuts, and consequently the distance apart of the concrete blocks, the rail bolt holes, and ultimately of the rails.

From time to time the nuts 10, 10, will be adjusted upon the boltsto locate bars 9 parallel, or to locate them more or less out of parallel, to position the concrete blocks at a maximum distance apart, or if desired closer together. Fine adjustment of block positions can be effected in this way. Holes 7, in the ends 7 and may be bored at The outside ends 7 of a rail-tie may be covered with ballast to complete the track, and later on can be uncovered and used as handles to facilitate any desired adjustment facilitate the assembly,

any appropriate time.-

both ends,

or removal of the rail-tie, or it it be desired ti elongatethe tie "as "next explained these projections can then be utilized. A Wooden rail tie is often moved by first driving a pick into itand thefi'using the pick as a handle or lever but that is not practicable With concrete ties.

In Figure 4 the extremity of block .1? is shown by dotted line 1 and the nearest extremity thereto of block 19 mentioned in the next paragraph is shown by dotted line .1". i

To elongate a tie bar, for use for example ata track intersection, atone or at I apply as thefcase may require, one or more extension blocks 1?, an end of which is shown in Figure 4. Each eX- tension blookis of any suitable transverse cross sectional form :or terms and length,

and carries embedded bars 7 having pro- The extension is to be placed in position l aving any distance desired between it and the nearest block 1 or'l the ends of the respective bars Which project from the blocks, being connected either directly to one another, as when they overlap, this not being illustrated but clearly to be'understood as a mechanically simple operation, or they are 'conneotedby .means of bars .9 and bolts as 9 and IOF'eaoh of any suitable length, when there is not such overlap. The space between the end jecting ends 7 of the block 1 and the adjacent block, is to be filled in any suitable obvious i'fnanner With concrete 11 so that the rail tie is made continuous.

1. A rail tie of the character described, comprising spaced blocks for supporting rails, said blocks having projections, normally parallel links connecting the projections of one block with those of the other, and means for adjustably forcing said links out of parallelism to reduce the space between the blocks.

2. A rail tie as claimed in claim 1, in-

said blocks and projecting from the latter to form said projections.

3. A rail tie as claimed in claim 1, said means comprising a transverse member carried by said links, and means carried by said transverse member for altering the space between said links.
